Rookie is the brand new webzine for teen girls from 15-year-old blogger Tavi (StyleRookie) Gevinson, who was born to reinvent Sassy for the digital age. If you haven’t seen it yet, what are you waiting for?

It’s smart, stylish and so fresh you’ll swear can see tear stains drying on the page. It’s also sensible beyond the years of its small army of young contributors, most of whom wrap their articles in first-person narratives. That’s Tavi’s illustration above for a feature on how girl-girl drama escalates — wonderful stuff.

There are fashion pieces too, of course, but they’re predictably wonky: one looks at how to dress like a 1950s tough chick, and there’s a terrific, crazy-long essay on one girl’s obsession with her Smiths/Morrissey t-shirt collection. And another gem: high-school survival tips from out-there celebs like Zooey Deschanel and Josh Whedon.

What’s missing? Makeup tips. Weight loss advice. Popstar pinups. And — not surprising given that its editor goes to sleep every night listening to Hole’s Live Through This — not a single reference to Justin Bieber. This ain’t your mama’s Tiger Beat, that’s for sure.

If you’re a teenage girl, prepare to learn more about yourself than you thought was possible. If you’re another fashion blogger like me, get used to TaviEnvy. If you own Disney stock, be worried.
